OWNZONE METHODS
Polar M71 ti uses multiple methods for determining your
safe OwnZone. The primary method is to measure and
analyse the heart rate variability and thereby determine
the most individual and current parameters.
If your heart rate exceeds the safety limit during the
determination, Polar M71 ti picks up your latest OwnZone
definition based on heart rate variability. Alternatively, if
there is no previous determination in memory, Polar M71 ti
will automatically calculate Target Zone limits which are
based on your age predicted maximum heart rate. These
methods ensure the safest possible exercising zone
determination for you.
The method used in defining the exercising Target Zone is
indicated after the two beeps as follows:
1. O.Z.V (OwnZone Variability) and the currently
determined OwnZone limits appear on the
illuminated display.
2. O.Z.L (OwnZone Latest) and your previously
determined OwnZone limits appear on the
illuminated display.
3. O.Z.A (OwnZone Age) and your age-predicted
heart rate limits appear on the illuminated display.
HOW TO USE PREVIOUSLY
DETERMINED OWNZONE
Every time you start the stopwatch and have the OwnZone
option on, Polar M71 ti starts finding your OwnZone. You
can determine your OwnZone for every exercise session
separately. At least it should always be performed when
changing exercise environment, exercise mode or if you
have abnormal feelings about your physiological state
when starting the exercise.
However, you can choose to exercise with the latest
OwnZone limits in case you are not willing to start the
process of redefining your OwnZone.
1. Start the heart rate measurement and stopwatch as
usual.

2. Press SET/START/STOP. Polar M71 ti starts using your
latest determined OwnZone.
O.Z.L and the values for your previously determined
OwnZone appear momentarily on the illuminated
display.
In case there is no previously determined OwnZone in
memory, Polar M71 ti starts using your age predicted
exercising limits.
O.Z.A and your age-predicted heart rate limits
appear on the illuminated display.
